Occasional weird inverter behaviour.
Our work setup is 50kW panels with a Solis inverter grid coupled to Sunsyk 50kW hybrid inverter with 96kWk battery without any panels.
Has been working well apart from a few random periods where the inverter will slowly discharge the battery but will not recharge the battery when there is lots of excess solar power being exported. There are lots of slowly repeating clicks coming from the Sunsynk inverter as though it is caught in some sort of system loop and the only way to reset it is to turn the inverter off and on again when it will carry on working normally.
I have a similar system at home but with 8kW inverter with 15kWh battery which works faultlessly.
Anyone had this problem or might know how to cure it?

Yes to the Micro inverter and yes the Solis is also 3 phase. Also Sunsynk ct's are at the grid connection point.
The system does work fine charging and discharging up to 30 kW (battery limited) but occasionally (3 or 4 times in the last few months) the inverter just sits quietly clicking away until it is reset by turning off and on again.
